Railway coupler shelf chamfer

Abstract

A railway coupler having a coupler head and a support shelf extending from the lower portion and in some couplers, from the upper portion as well, of the coupler head is provided. A chamfer is provided on the front and side edges of the support shelf and also on the front and side edges of the auxiliary interlocking lug to decrease the possibility of the raising of one coupler during an adverse vertical angling coupling operation.

What is claimed is: 
     
       1. A railway car coupler comprising a head including a throat portion, a knuckle pivotally connected to the head at one side of the longitudinal vertical centerplane of the head, a generally planar, lower shelf extending from the head below the knuckle, said lower shelf extending from an intersection with the throat to a point substantially adjacent the pivot of the knuckle, said lower shelf having a front edge surface and a side edge surface, and a chamfer on the side edge surface and part of the front edge surface of the lower shelf, said chamfer extending downwardly and away from the guard arm side of the coupler head on the edge surface and downwardly and toward the coupler throat on the front edge surface.
